Answer:
B, C, Dand E are all correct
Explanation:
Why B is correct- The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit.
Plants, animals, and bacteria have a cell membrane. Why d is correcect
Why C is correct- The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.
Why E is correct- The plasma membrane is primarily composed of phospholipids arranged in a bilayer, with the hydrophobic tails on the interior of the membrane, and the hydrophilic heads pointing outwards
Why A Is Not correct- It is very fragile and its role is to hold the cell together and to help control what substances can get in and out. It is partially permeable, allowing only some substances to pass through it. The membrane has a complex structure consisting of a phospholipid bi-layer and different types of proteins.

Answer options are
✅Homogeneous housing -
✅Familiarity with the breed
✅Business efficiency
✅Standardized food supply
Lack of training ❌
Time demands❌
✅Personal preference
Reasons
I’m using beef cattle to determine these answers.
I chose the ✅ answers because of the following
✅ Homogenous housing. If you live in extremely cold or hot climates, you want livestock that can withstand cold temperatures for housing reasons. Hereford and Angus are hearty and survive cold temps, Brahman are warm weather cattle.
✅Being familiar with the breed makes raising that breed easier. For example if you know Angus beef cattle and not Chalais dairy cows, you won’t know the Chalais’s unique characteristics.
✅Business efficiency - having one brand or one breed in this instance will save in time, management, food supply, medicines, etc. Different breeds will require different nutrients and feed, different housing requirements, for example.
✅ Standardized food supply. Again, different breeds require different nutrients. Having just one breed will keep food supply simple.
✅ personal preference. Although this might not be a sound business practice, people tend to stick with things they know and like.
